func (*Bitmap) Clear ¶

func (n *Bitmap) Clear()

func (*Bitmap) Clone ¶ added in v0.6.0

func (n *Bitmap) Clone() *Bitmap

func (*Bitmap) Contains ¶

func (n *Bitmap) Contains(row uint64) bool

Contains returns true if the row is contained in the Bitmap

func (*Bitmap) InitWithSize ¶ added in v0.8.0

func (n *Bitmap) InitWithSize(len int64)

func (*Bitmap) IsEmpty ¶

func (n *Bitmap) IsEmpty() bool

IsEmpty returns true if no bit in the Bitmap is set, otherwise it will return false.

func (*Bitmap) IsSame ¶ added in v0.6.0

func (n *Bitmap) IsSame(b *Bitmap) bool

func (*Bitmap) Iterator ¶
